The voltmeter that Lied!


A component isn’t working, so you hook up your voltmeter and discover you have system voltage. You turn the component on and still see system voltage, but the component doesn’t run. You assume the component is faulty so you change it?

But it still doesn’t work – so now what? Why didn’t it work?

The answer is simple: your voltmeter can’t ‘see’ – and therefore can’t ‘tell’ you there is a high resistance in the circuit, or that changing the component will change nothing. You simply wasted the time it took to locate, collect and change a perfectly serviceable component – ‘thanks’ to your voltmeter!

So the voltmeter lied? Well – Yes! It ‘lied’ because it wasn’t designed to ‘see’ high resistance in the wiring - even though that is one of the most common occurrences in circuit faults.

So what’s the answer? An ohmmeter? NO! – that won’t tell you what you need to know, which is: can the circuit carry load; or can it carry current.

TESlite Voltmeter Leads will give you the answer you need at the push of a button, in just seconds.

Shocking – but true! So before you next need to rely on your voltmeter, treat your meter to a set of TESlite Voltmeter Leads and get right first time results.

Then watch the video below where the inventer of the Teslite (a mechanic) talks about how Testlite works!
